Nosler has always been a "premium" bullet to me. Premium always comes at a greater cost. A cost that is worth it if you need a premium bullet.
I hunt deer, elk and sometimes black bear and have no need for premium bullets. Speer "hot core" have always been accurate and performed well on the game.
I have tried them and they shoot well but what they do to a deer when shot through the shoulder is a shame. I stll have a partial box of lathe turned partitions that I keep as a reminder that I have little need for premium bullets.
My 6mm Remington "loved" the old 95 gr. Partition...as did I, it also shot out of my .244 Remington pretty well.They can be a little different, having a slight taper that some guns like and some don't. I always look at them as another thing to try if my regular choices (Sierra and Hornady, mostly, with an occasional Berger or Barnes or JLK) isn't tickling the gun's fancy.
Now that Hornady has gone HAP happy, the Nosler #44964 is, I think, the only truncated cone FMJ being made.
